So I've been in this hobby for about 5 years, and have only been doing water changes once every 3 or 4 months. And today I was wondering - why even do those? All of my coral/anemones are doing great, algae is controlled by chaeto and skimming. Anything toxic will be pulled by carbon/phosgaurd. A lot of posts on here talk about changing water every week or few days, which makes me think that I am missing something? The only thing I can think of is trace elements, but if they are that important we should be dosing them anyway? Alk/Ca2+ are basically the only thing I ever dose. I am curious to hear your thoughts on this, I feel like I am overlooking something but can't put my finger on it.
